Sniper...I think I have had all the versions of rashes and hives and welts. I really do think it is an immune issue. The last two docs said I had lab results that showed different viral issues - mostly dormant things that can be triggered by just about
anything. The time I had raised welts/hives, that was also noted as a virus but not by lab test-rather they matched the book pictures my doc pulled out about
pityasis-yea sounds like a pitiful disease!
The last few incidents have been the terribly itchy patches like you described and they multiplied fast. Since then i get a random spot that itches like crazy, then turns beige and stays on my skin forever (well I'm not dead yet, so forever is debatable
I have yet to figure out the cause and lately I have just surrendered to be a patchy mess by the time I reach 90 (OK so maybe I am pushing my luck there!) Some day I will actually make it to a dermatologist so he can tell me he has no idea why I get them too
Dx'd '90 (emergency rupture), symptoms ignored long before that, '03 fistulas and bad flagyl reactions, B12 weekly, Pentasa [until I surrender to the bigger meds]
